Hi,

This used to work:

<telerik:RadTransitionControl
            HorizontalContentAlignment="Stretch"
            VerticalContentAlignment="Stretch"
            Margin="10,0,0,0"
            Content="{Binding EventContent}">
            <telerik:RadTransitionControl.Transition>
                <telerikTransitions:RollTransition IsRollOut="True" IsTopToBottom="False" />
            </telerik:RadTransitionControl.Transition>
        </telerik:RadTransitionControl>

with 2022 update the control no longer shows *anything*

For testing, I hardcoded the Content:

        <telerik:RadTransitionControl
            HorizontalContentAlignment="Stretch"
            VerticalContentAlignment="Stretch"
            Margin="10,0,0,0">
            <TextBlock Foreground="Aqua" FontSize="44">This is a test</TextBlock>
            <telerik:RadTransitionControl.Transition>
                <telerikTransitions:RollTransition IsRollOut="True" IsTopToBottom="False" />
            </telerik:RadTransitionControl.Transition>
        </telerik:RadTransitionControl>

This showed the textbox while in Design mode, but when the app ran, nothing was displayed

I rolled back to R2021.3.1109.45 and it works again.

These updates are getting more and more painful :/

Hello Eric,

Thank you for the shared code snippets. 

I tested the scenario in a sample project referencing the 2022.1.117 version of the dlls on my end, however the RadTransitionControl is displayed as intended. You can check out the attached sample project, which I used for testing. 

Note, that if the NoXaml dlls are used, a theme dll must be referenced and also all of the required resource dictionaries must be merged in order for the controls to be displayed. You can check, which version of the dlls is being used by following these tips

I hope you find this helpful. Let me know, if I can be of any further assistance. 

Regards,
